Towa is shown to be willing to go as far as deceiving God of Destruction Beerus by pretending to be Chronoa and her acting was so convincing that she managed to fool both Beerus and Whis, causing them to leave Age 779 during Frieza's Revenge without them realizing her deception until they arrived in Age 852, preventing Whis from assisting Goku and his friends. Mira has no fear, as he wants to be the strongest. By all means.
